7 In this mode a self-test is initiated during power-on or by a Reset command. After reset signal, PS/2 mouse will send: (a) Completion code AA & ID code 00. (b) Set default : sampling rate: 100 reports/s non-auto speed stream mode 2 dot/count disable b. Stream Mode The maximum rate of transfer is the programmed sample rate. Data report is transmitted if (a) switch is pressed (b) movement has been detect c. Remote Mode Data is transmitted only in response to a Read Data command. d. Wrap Mode Any byte of data sent by the system, except hex EC ( Reset wrap mode ) or hex FF ( Reset ), is returned by PS/2 Mouse Data Report i). In stream mode: A data report is sent at the end of a sample interval. ii). In remote mode: A data report is sent in response to Read Data command. iii). Data report format: Byte Bit Description 1 0 Left button status; 1 = pressed 1 Right button status; 1 = pressed 2 Middle button status; 1 = pressed 3 Reserve 4 X data sign; 1 = negative 5 Y data sign; 1 = negative 6 X data overflow; 1 = overflow 7 Y data overflow; 1 = overflow X data ( D0 - D7 ) Y data ( D0 - D7 ) Page 7 of 17

8 6.1.3 PS/2 mouse Data Transmission i). generates the clocking signal when sending data to and receiving data from the system. ii). The system requests receive system data output by forcing the DATA line to an inactive level and allowing CLK line to go to an active level. iii). Data transmission frame: Bit Function 1 Start bit ( always 0 ) 2-9 Data bits ( D0 - D7 ) 10 Parity bit ( odd parity ) 11 Stop bit ( always 1 ) iv). Data Output (data from to system): If CLK is low (inhibit status), data is no transmission. If CLK is high and DATA is low (request-to-send ), data is updated. Data is received from the system and no transmission are started by until CLK and DATA both high. If CLK and DATA are both high, the transmission is ready. DATA is valid prior to the falling edge of CLK and beyond the rising edge of CLK. During transmission, check for line contention by checking for an inactive level on CLK at intervals not to exceed 100u sec. Contention occurs when the system lowers CLK to inhibit output after has started a transmission. If this occurs before the rising edge of the tenth clock, internal store its data in its buffer and returns DATA and CLK to an active level. If the contention does not occur by the tenth clock, the transmission is complete. Following a transmission, the system inhibits by holding CLK low until it can service the input or until the system receives a request to send a response from. v). Data Input ( from system to ): System first check if is transmitting data. If is transmitting, the system can override the output forcing CLK to an inactive level prior to the tenth clock. If transmission is beyond the tenth clock, the system receives the data. If is not transmitting or if the system choose to override the output, the system force CLK to an inactive level for a period of not less than 100u sec while preparing for output. When the system is ready to output start bit (0), it allows CLK go to active level. If request-to-send is detected, clocks 11 bits. Following the tenth clock checks for an active level on the DATA line, and if found, force DATA low, and clock once more. If occurs framing error, continue to clock until DATA is high, then clocks the line control bit and request a Resend. When the system sends out a command or data Page 8 of 17

9 transmission that requires a response, the system waits for to response before sending its next output PS/2 Mouse Error Handling i). A Resend command ( FE ) following receipt of an invalid input or any input with incorrect parity. ii). If two invalid input are received in succession, an error code of hex FC send to the system. iii).the counter accumulators are cleared after receiving any command except Resend. iv). receives a Resend command(fe), it transmit its last packet of data.. v). A response is sent within 25 ms if a). The system requires a response b). An error is detected in the transmission iv). When a command requiring a response is issued by the system,another command should not be issue until either the response is received or 25ms has passed. 6.2PS/2 Mouse Commands Description There are 16 valid commands that transmits between the system and. The FA code is always the first response to any valid input received from the system other than a Set Wrap Mode or Resend command. The following table list the commands: Hex Code Command echo code FF Reset FA,AA,00 FE Resend XX,(XX,XX) F6 Set Default FA F5 Disable FA F4 Enable FA F3,XX Set Sampling Rate FA,FA F2 Read Device Type FA,00 F0 Set Remote Mode FA EE Set Wrap Mode FA EC Reset Wrap Mode FA EB Read Data FA,XX,XX,XX EA Set Stream Mode FA E9 Status Request FA,XX,XX,XX E8,XX Set Resolution FA,FA E7 Set Autospeed FA Page 9 of 17

10 E6 Reset Autospeed FA The following describes valid commands: a). Reset ( FF ) operation: i). Completion the reset. ii). Transmitted FA,AA,00 to the system. iii). Set default: sampling rate: 100 reports/s non-autospeed stream mode 2 dots/count disable b). Resend ( FE ) i).any time receives an invalid command, it returns a Resend command to the system. ii).when receives a Resend command, it retransmits its last packet of data.if the last packet was a Resend command, it transmits the packet just prior to the Resend command. iii).in stream mode, if a Resend command is received by immediately following a 3-byte data packet transmission to the system. iv).the ACK(FA) byte sent to acknowledge a command is not stored in any buffer or resent; however, if the last output from the device was an ACK with no additional data bytes,resend responds with an ACK. c). Set Default ( F6 ) The command reinitializes all conditions to the power-on defaults. d). Disable ( F5 ) This command is used in the stream mode to stop transmissions from. e). Enable ( F4 ) Begins transmissions, if in stream mode. f). Set Sampling Rate ( F3,XX ) In the stream mode, this command sets the sampling rate to the value indicated by byte hex XX, show in following: Page 10 of 17

11 Second byte XX Sample Rate 0A 10/sec 14 20/sec 28 40/sec 3C 60/sec 50 80/sec /sec C8 200/sec g). Read Device Type ( F2 ) always echoes FA,00 in 2D mode, FA,03 in 3D mode. h). Set Remote Mode ( F0 ) Data value are reported only in response to a Read Data command. i). Set Wrap Mode ( EE ) Wrap mode remains until Reset ( FF ) or Reset Wrap Mode( EC ) is received. j). Reset Wrap Mode ( EC ) returns to the previous mode of operation after receiving this command. k). Read Data ( EB ) This command is executed in either remote or stream mode. The data is transmitted even if there has been no movement since the last report or the button status is unchanged. Following a Read Data command, the registers are cleared after a data transmission. l). Set Stream Mode ( EA ) This command sets in stream mode. m). Status Request ( E9 ) When this command is issued by the system, respond with a 3-byte status report as follows: Byte Bit Description = Right button pressed 1 1 = Middle button pressed 2 1 = Left button pressed 3 Reserved 4 0 = Normal speed, 1 = Autospeed 5 0 = Disabled, 1 = Enabled 6 0 = Stream mode, 1 = Remote mode 7 Reserved Current resolution setting ( D0 - D7 ) Current sampling rate ( D0 - D7 ) Page 11 of 17

12 n). Set Resolution ( E8,XX ) provides four resolutions selected by the second byte of this command as follows: Second Byte XX Resolution 00 8 dot/count 01 4 dot/count 02 2 dot/count 03 1 dot/count o). Set Auto speed ( E7 ) At the end of a sample interval in the stream mode, he current X and Y data values are converted New values. The sign bits are not involved in this conversion. The conversion is only in stream mode. The relationship between the input and output count follows: Input Output N( 6) 2.0*N p). Reset Auto speed ( E6 ) This command restore normal speed. 6.3Microsoft PS/2 scrolling mouse mode (A) Entering procedure: Except in WRAP mode, while received the following consecutive command. i. F3 C set sampling rate 200/sec ii. F set sampling rate 100/sec iii. F set sampling rate 80/sec (B) Operating: a. All of the commands in 2D mode still be valid. b. The ID code of read device type command (F2) will changed from "00" to be "03". c. Data report will be four bytes format: Byte Bit Description 1 0 Left button status; 1 = pressed Page 12 of 17

Power off. b. Reset command (FF). 6.4 Z-axis Input Function Photo Couples Input Z-axis counter accumulates the Z1, Z2 phase changed by movement. This mode includes noise immunity. Z/4 : 4 dots per count. Counted by Z1=1, Z2=1 phase, the wheel should stay at Z1=0, Z2=0 phase Mechanical Mode The function is the same as photo couples input mode, except there is no noise immunity. Z/2 : 2 dot per count. Counted by Z2 changing phase. 7. ABSOLUTE MAXIMUM RATING Parameter Sym. Min. Max.
